Amabhethri enkinobho ye-lithium ngokuyinhloko enziwe ngensimbi ye-lithium noma i-lithium alloy njenge-anode ne-carbon material njenge-cathode, nesisombululo se-electrolyte esenza ama-electron ageleze phakathi kwe-anode ne-cathode.
Izinto ze-Cathode ezisetshenziswa kumaseli we-lithium coin zingahluka.Izinto ezisetshenziswa kakhulu ze-cathode zamabhethri e-lithium inkinobho yi-lithium cobalt oxide (LiCoO2), i-lithium manganese oxide (LiMn2O4) ne-lithium iron phosphate (LiFePO4).Ngayinye yalezi zinto ze-cathode inesethi yayo eyingqayizivele yezakhiwo ezenza ifanele izinhlobo ezahlukene zezicelo.
I-Li-SOCL2 iyibhethri ethandwa kakhulu, futhi i-pkcell iqhubeke ithuthukisa ukusebenza kahle kwe-Li-SOCL2 eminyakeni yocwaningo nentuthuko, futhi iye yaqashelwa amakhasimende amaningi.
I-Lithium cobalt oxide (i-LiCoO2) iyinto esetshenziswa kakhulu ye-cathode kumabhethri enkinobho ye-lithium.Inomthamo omkhulu wamandla kanye nempilo yomjikelezo omude uma kuqhathaniswa, okusho ukuthi ingashajwa futhi isetshenziswe izikhathi eziningi ngaphambi kokulahlekelwa umthamo.Kodwa-ke, futhi kuyabiza kakhulu kunezinye izinto ze-cathode.
I-Lithium manganese oxide (LiMn2O4) enye into evamile ye-cathode esetshenziswa kumaseli ezinhlamvu ze-lithium.Inokuminyana kwamandla okuphansi kune-LiCoO2, kodwa izinzile futhi ayijwayele ukushisisa ngokweqile.Lokhu kuyenza ilungele izinto ezilambele amandla njengamakhamera edijithali nezidlali ze-CD eziphathwayo.I-Li-MnO2 Ibhethri ingelinye lamabhethri aziwa kakhulu ku-PKCELL
I-Lithium iron phosphate (LiFePO4) iyinto entsha ye-cathode ethola ukuduma kumabhethri eseli ye-lithium coin.Inokuminyana kwamandla okuphansi kune-LiCoO2 ne-LiMn2O4, kodwa izinze futhi iphephe kakhudlwana, inengozi ephansi kakhulu yokushisa ngokweqile noma yomlilo.Ukwengeza, inokuqina okuphezulu kwe-thermal kanye namakhemikhali, okwenza ifanele izinga lokushisa eliphezulu kanye nezicelo zamandla aphezulu.
I-electrolyte esetshenziswa kumabhethri enkinobho ye-lithium ingaba uketshezi noma iqine.Ama-electrolyte awuketshezi asetshenziswa ngokuvamile usawoti we-lithium kuzincibilikisi eziphilayo, kuyilapho ama-electrolyte aqinile kungusawoti we-lithium oshumekwe kuma-polymer aqinile noma izinto ezingaphili.Ama-electrolyte aqinile ngokuvamile aphephile kunama-electrolyte awuketshezi.
